I can see how it'd be somewhat less interesting to a modern audience than its great rival at the time, All About Eve, and its stars have stood the test of time less well. But as a commentary on Hollywood and on the relativity of fame, it's a very good movie with a few very memorable scenes and quotes.

The Graduate on the other hand is not just a little, but massively overrated (I have rarely seen as annoying a character as Dustin Hoffman's), the only good thing about that movie is the Simon & Garfunkel soundtrack (not just Mrs. Robinson, just about all the hits are played at some point).

And Apocalypse Now, while doubtlessly very important and all, is mostly a snorefest. The best scenes are in the beginning tbh, after that it just gets boring, and then there's Marlon Brando being fat and weird.
